Statistical Investigation of Connected Structures of Stock Networks in Financial Time Series

摘要: In this study, we have investigated factors of determination which can affect the connected structure a stock network. The representative index for topological properties network is number links with other stocks. We used multi-factor model, extensively acknowledged in financial literature. common act as independent variables while returns individual stocks dependent variables. calculated coefficient determination, represents measurement value degree are explained by Therefore, relationship between and model. traded on market indices Korea, Japan, Canada, Italy UK. results follows. found that mean large higher values than those small These suggest significantly deterministic to be taken into account when making Furthermore, more affected factors.
